portion. The valveisprovided with spaced ports 2. A fluid distributing device, comprising a 55 ber, said heads cooperating to alternately cover body having a central and end portions, a bore running longitudinally in the central portion of said body, concentric bores running longitudinally in the end portions of said body, movable sealing means in said central portion bore, adjacent inlets and outlets on ends of said body portion communicating with said bores, by-passages in said end-portions connecting said inlets with said central portion bore, valve means adapted to cover and uncover said by-passages and outlets, but positioned to longitudinally receive fluid pressure from said inlets, said valve means adapted to control the flow of fluid from the inlets to the outlets.

3. Apparatus for distributing fluid under pressure flowing alternately from a plurality of sources comprising a body having an inlet and an adjacent outlet for each of said sources, and means in said body measuring fluid under pressure then entering at one of said inlets without permitting communication with the outlet adjacent thereto, and simultaneously closing the inlet not then receiving fluid under pressure and utilizing the pressure of said inflowing fluid to force a previously measured quantity of fluid from the outlet adjacent to said last-named inlet, said means being operated to automatically reverse said operations upon alternating the source of fluid under pressure.

4. In apparatus of the class described, a body portion having inlets and outlets, concentric bores in said portion, an annular piston in at least one of said bores, valve headsin said other bores, a stem joining said heads and passing through said annular piston, such body having by-passages associated with said heads, said heads being each arranged to alternatively cover and uncover the outlet passages and the by-passages.

5. In apparatus of the class described, a central body portion, endwise body portions, means Ior coupling said body portions permitting angular adjustments thereof, said body portions having concentric bores, a floating member in the bore of the central body portion adapted to seal incoming material from outgoing material, inlets and outlets on said endwise portions, by-passages in endwise portions connecting said inlets and central body portion, valve heads in said endwise body portion bores, a stem connecting said heads and passing through said floating memand uncover said by-passages and outlets, said floating member cooperating to receive material from a by-passage and eject material from an outlet, fluid under pressure entering one inlet moving said valve heads to open the one by passage, close the adjacent outlet, open the opposite outlet and close the other by-passage,

the fluid entering the bore containing the floating member operating said member to force the fluid through said opposite outlet.

6. In apparatus of the class described, a central body portion, endwise body portions, means for coupling said body portions permitting angular adjustments thereof, said body portions having concentric bores, a floating member in the bore of the central body portion adapted to seal incoming material from outgoing material, inlets and outlets on said endwise portions, lay-passages in endwise portions connecting said inlets and central body portion, valve heads in said endwise body portion bores, a stem connecting said heads and passing through said floating member, said heads cooperating to alternate- 1y cover and uncover said by-passages and outlets and said floating member transferring pressure from said inlets to said outlets, fluid under pressure entering one inlet moving said valve heads to open the one by-passage, close the adjacent outlet, open the opposite outlet and close the other by-passage, the fluid entering the bore containing the floating member operating said member to force the fluid through said opposite outlet. t

7. Apparatus for distributing fluid under pressure flowing alternately from several sources comprising a body having an inlet and an adjacent outlet for fluid corresponding to each fluid source, valve means in said body operated by fluid under pressure at said inlets applied to the heads of the valve, said valve means delivering measured quantities of fluid from an inlet to a position for delivery from the outlet adjacent said inlet, and movable means in said body operated by fluid under pressure entering at an inlet to force said measured quantities of fluid from an outlet not adjacent said last-named inlet.

8. In apparatus of the class described, a body portion having a pair of inlets and an outlet adjacent to each inlet, concentric bores in said portion, an annular piston in one of the said bores, a valve structure comprising valve heads in said other bores and a stem joining said heads passing through said annular piston, said body having by-passages connecting said inlets to the bore containing said annular piston, said heads being arranged to alternately cover and uncover the outlet passages and by-passages, fluid under pressure entering one inlet moving said valve heads to open the one by-passage, close the adjacent outlet, open the opposite outlet and close the other by-passage, the fluid entering the bore containing the floating member, operating said member to force the fluid through said opposite outlet.
